Range table example

Many nonstandard uses of ACEEIEP are possible. This example illustrates how to convert one possible nonstandard use into a range table.

Suppose you wish to compress an ACEE that is configured as follows:

where:

NAMEPTR, SSNPTR, and INFOPTR are pointers to the actual data.
NAME and NAMELEN are the full name and length of name of a person.
SSN is a 9-character Social Security number.
INFO and INFOLEN are miscellaneous data and the length of this data.

At compression time, the information pointed to by ACEEIEP must be converted into the following range table:

00000003                    * Range count
000000FF                    * Subpool

NAMEPTR+1                   * Pointer to start of first range
NAMEPTR+NAMELEN             * Pointer to end of first range

SSNPTR                      * Pointer to start of second range
SSNPTR+9                    * Pointer to end of second range

INFOPTR+1                   * Pointer to start of third range
INFOPTR+INFOLEN             * Pointer to end of third range
